CRRC PDTY532X Series Wire Drawing Machine Motor

CRRC PDTY532X series is a mid-torque wire drawing machine motor tailored for mainstream metal wire processing scenarios, delivering a torque range of 0-1080 Nm and a speed range of 0-785 rpm (within the 15-75kW power range), paired with low noise and reliable operational stability.
Equipped with optimized heat dissipation channels, this motor is engineered to maintain consistent performance under the dynamic load fluctuations of medium-diameter wire drawing (e.g., standard iron/precious metal wires).
As a widely adopted model in domestic metal processing enterprises, it integrates seamlessly with most mid-scale wire drawing production systems, ensuring compatibility with industry-standard processing equipment.
We offer comprehensive life-cycle support for the PDTY532X series, including equipment supply, on-site installation and commissioning, maintenance training, spare parts provision, and ongoing technical troubleshooting services.

Advantages of CRRC PDTY532X Series Wire Drawing Machine Motor

This wire drawing motor series covers a 15-75kW power range and 5 distinct torque/speed combinations, enabling broad application compatibility that adapts to fine, medium, thick, heavy-gauge, and extra-thick wire drawing processes for materials including copper, aluminum, iron, and precious metals.
Its precision design—featuring a balanced rotor and optimized heat dissipation—ensures stable & high-quality output, delivering consistent power delivery to reduce wire diameter deviation and improve finished product qualification rates.
With structural damping and a compact frame, the motor adopts a low-noise & lightweight design: this minimizes workshop noise pollution, while the lightweight construction lowers the load of equipment installation and daily operation.
Built with reinforced components like bearings and conductors to extend service life, the motor also features a modular layout that enables durable & easy maintenance, supporting quick disassembly, part replacement, and routine upkeep.
Boasting proven market reliability, over 1,000 units have been deployed in domestic metal processing enterprises; mature quality control systems further guarantee stable performance and consistent supply for end users.
